BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an image forming apparatus including an operating means for designating the size of sheets for manual feeding as a device or a job, and/or a reserved printing function that accepts reservations made for subsequent image forming jobs during image formation, an image forming system, a sheet feeding source designation control method, an image formation control method, and storage media storing programs for executing the methods.

[0003] 2. Related Art

[0004] An image forming apparatus is known, which includes means for designating the size of sheets for manual feeding as a device (manual sheet feeder type designating means), means for designating the size of sheets for manual feeding as a job (designating means through an operation panel), and means for designating manual feeding as a method of feeding sheets used for copying originals, and performing copying operations based on instructions given by these means (first prior art).

[0005] On the other hand, of various functions performed by an image forming apparatus, reserved copying is known, wherein a next process of inputting images is executed during printing in order to perform print jobs efficiently. Further, with respect to settings for performing printing, the conventional image forming apparatus enables users to use types of sheets requiring respective different processes, such as an OHP sheet and a thick sheet, in addition to an ordinary sheet, by providing settings corresponding respectively to such different processes (second prior art). In the conventional image forming apparatus, a print job is executed based on the user's designation of a sheet cassette through which a sheet or sheets are to be supplied.

[0006] However, the above conventional image forming apparatuses have the following problems: In the first prior art, a print job using manual feeding needs designating a sheet size for manual feeding by using the manual feeding sheet size designating means, and designating a sheet cassette by using the manual feeding designating means. When the user considers by mistake that he or she has selected the sheet cassette together with the sheet size upon designation of the sheet size, i.e. when the user has designated only the sheet size, but not the sheet cassette, the image forming apparatuses may sometimes execute the print job using sheets fed through an undesired sheet cassette.

[0007] Further, in the second prior art, as mentioned above, a print job is executed based on the user's designation of a sheet cassette through which a sheet or sheets are to be supplied. To execute a print job using a sheet or sheets from a manual feed tray mounted on the image forming apparatus, for example, the user cannot designate the size and type of sheet for printing jobs to be reserved, and determines whether or not a sheet or sheets are on the manual feed tray when he or she sets each print job. This makes it difficult for the image forming apparatus to smoothly execute different manners of printing through manual feeding (for example, printing processes including manual feeding of A-size ordinary sheets, and special sheets such as postcards and OHP sheets) according to a plurality of print jobs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0058] The present invention will now be described with reference to the drawings showing embodiments thereof.

[0059] First, a description will be given of a first embodiment. The first embodiment is characterized in that if a user sets a sheet size by means of a device or a job, it is determined whether or not a manual feed tray can be designated as a sheet feeding source, and when it is so determined, the manual feed tray is designated as the sheet feeding source, and further, if the user sets a sheet size by means of a device or a job, a sheet selecting screen is displayed on a touch panel of an operating section, which allows the user to confirm/change the designation of the manual feed tray as the sheet feeding source, upon completion of the sheet size designation.

[0060]FIG. 1 is a block diagram showing the arrangement of a digital copying machine (image forming apparatus) according to the first embodiment. The digital copying machine according to the first embodiment is comprised of a digital copying machine main body 101 having an operating section 102, a reader section 103, and a printer section 104, and an image input/output controller section 105 having a facsimile section 106, a computer interface section 107, an image memory 108, and a control section 109. The control section 109 of the image input/output controller section 105 is connected to the reader section 103 of the main body 101. In FIG.1, reference numeral 110 designates a personal computer or a work station (hereinafter referred to as PC/WS), and reference numeral 120 designates a telephone line. While the digital copying machine is taken as an example of the image forming apparatus, digital copying machines are not the sole application of the invention.

[0061] The above configuration will now be described in detail. In the digital copying machine main body 101, the operating section 102 is used to operate the digital copying machine main body 101 and the image input/output controller section 105, and is provided with various keys, a touch panel, and others, as described hereinafter. The reader section 103 reads the image of an original set on the digital copping machine and sends image data corresponding to the image of the original to the printer section 104 and the image input/output controller section 105. T reader section 3 has a construction shown in FIG. 2, described hereinafter. The printer section 104 records (prints) the image corresponding to the image data from the reader section 103 and the image input/output controller section 105, and has a construction shown in FIG. 2, described hereinafter.

[0062] In the image input/output controller section 105, the facsimile section 106 expands compressed image data received via the telephone line 120, transfers the expanded image data to the control section 109, and further compresses image data transferred from the control section 109 and transmits the compressed image data via the telephone line 120. The compressed image data received by the facsimile section 106 can be temporarily stored in the image memory (hard disk) 108. The computer interface section 107 interfaces the PC/WS 110 with the control section 109, and expands code data PDL (Page Description Language) representing an image transferred from the PC/WS 110 into image data that can be recorded by the printer section 104, and delivers the expanded data to the control section 109. The image memory 108, which is formed of a hard disk or the like, stores the image data.

[0063] The control section 109 controls the flow of data between the reader section 103, facsimile section 106, computer interface section 107, and image memory 108, and supervises various kinds of display control, described hereinafter, over the touch panel (see FIG. 3) of the operating section 102 based on programs of the invention. Further, the control section 109 controls the image memory 108 to sequentially store input image data, and the printer section 104 to sequentially print out hard copies of the image. The section 109 also controls a process of determining whether or not a manual feed tray 222 can be selected as the sheet feeding source if the user designates a sheet size by means of a device or a job, and selecting the manual feed tray 222 as the sheet feeding source if it is so determined, and a process of displaying a sheet selecting screen on the touch panel 316 of the operating section 102. if the user designates a sheet size by means of a device or a job, to allow the user to confirm/change the selection of the manual feed tray 222 as the sheet feeding source, upon completion of the sheet size designation. Further, the control section 109 executes processes shown by flowcharts in FIGS. 13 and 14.

[0064] The PC/WS 110 data-communicates with the computer interface section 107 provided on the image input/output controller section 105 of the digital copying machine, and transfers the above-mentioned image-representing code data (PDL) to the control section 109 via the computer interface section 107 of the digital copying machine.

[0065]FIG. 2 is a view showing the internal structure of the reader section 103 and the printer section 104 of the digital copying machine according to the first embodiment. The reader section 103 of the digital copying machine according to the first embodiment is comprised of an original feeder (RDF) 201, a platen glass (original table glass) 202, a lamp 203, a scanner unit 204, mirrors 205, 206 and 207, a lens 208, and a CCD image sensor (hereinafter referred to as the “CCD”) 209. The printer section 104 is comprised of a laser beam projector section 210, a photosensitive drum 211, a developing unit 212, cassettes 213 and 214, a transfer section 215, a fixing section 216, discharge rollers 217, a flapper 218, a re-feeding path 219, a sorter 220, a laser driver 221, and a manual feed tray 222. While FIG. 2 shows only two cassettes for the sake of convenience, five cassettes are provided, for example, in the first and second embodiments of the present invention as described hereinafter. Further, the number of cassettes is not limited to five.

[0066] The above construction will be described in detail together with the operation thereof. In the reader section 103, the original feeder 201 feeds originals onto the platen glass 202 one by one from last to first. After having read all the originals, the feeder 201 discharges them from the platen glass 202. Upon feeding the originals onto the platen glass 202, the lamp 203 is turned on, and then the scanner unit 204 is activated to scan the originals by projecting a beam of light over them. The light reflected from each original is guided to the CCD 209 by the mirrors 205, 206, 207 and the lens 208. The image of each original scanned as described above is read by the CCD 209. The image data from the CCD 209 is then subjected to a predetermined process, and the processed data is further stored in storage means such as the hard disk for subsequent transfer to the printer section 104 and the control section 109 of the image input/output controller section 105.

[0067] In the printer section 104, the laser driver 221 drives the laser beam projector section 210 to project a laser beam corresponding to the image data from the reader section 103. The laser beam is irradiated on the photosensitive drum 211 to form, on the drum 211, a latent image corresponding to the laser beam. The developing unit 212 deposits a developer on the latent image portion of the photosensitive drum 211. Then, in timing synchronous with the start of projecting the laser beam, a recording sheet is fed to the transfer section 215 from either the cassette 213 or 214 to transfer the developer deposited on the photosensitive drum 211 onto the recording sheet. The recording sheet having the developer transferred thereon is then fed to the fixing section 216, where the developer is fixed to the recording sheet by heat and pressure from the section 216. The recorded sheet having passed through the fixing section 216 is then discharged by the discharge rollers 217. The sorter 220 sorts the discharged recorded sheets into bins thereof, and staples them if so required. The manual feed tray 222 is used to manually feed sheets.

[0068] When a sorting mode is not set, the sorter 220 stacks recorded sheets on its uppermost bin. When a double-sided recording mode is set, a recording sheet having data recorded on one side thereof is fed to a location where the discharge rollers 217 are arranged, and then the discharge rollers 217 are reversely rotated to cause the flapper 218 to guide the sheet to the re-feeding path 219. When a multiple recording mode is set, a recording sheet is guided to the re-feeding path 219 by the flapper 218 so as not to be fed to the discharge rollers 217. The recording sheet guided to the re-feeding path 219 is then fed to the transfer section 215 in the above-mentioned timing. Even during printing, the reader section 103 can accept a request for the next reading operation immediately when it has finished the previous reading operation. The data from the reader section 103 is stored in the storage means, such as the hard disk.

[0069]FIG. 3 is a front view showing the arrangement of keys and touch panel of the operating section 102 of the digital copying machine according to the first embodiment.

[0076] Reference numeral 414 designates a double-sided copy settings displaying area, which displays types of double-sided copying when the user sets a double-sided copying mode (when the double-sided copy key 412 is highlighted). Reference numerals 420 and 415 designate favorite keys. When a favorite function 1 is set in the operator mode, the favorite key 420 is displayed, while when a favorite function 2 is set, the favorite key 415 is displayed.

[0077]FIG. 5 is a view showing the copy application mode screen 400 b displayed on the touch panel (liquid crystal display operating section) 316 of the digital copying machine according to the first embodiment. The application mode screen 400 b is displayed when the application mode key 413 is depressed as mentioned above. Reference numeral 430 designates a border erasing key depressed to erase borders according to any of set modes, such as a sheet border erasing mode (creating a border corresponding to a sheet size), an original border erasing mode (creating a border corresponding to an original size and designating the original size), a book border erasing mode (creating a border and gutter margins corresponding to a spread size of a book and designating the spread size), a punch hole erasing mode (processing portions corresponding to punch holes in the original into white space to prevent the punch holes from turning black in the copied sheet).

[0078] Reference numeral 431 designates a binding margin key depressed to set a binding margin to any of four different margins, i.e. left, right, top, and bottom of sheet. Reference numeral 432 designates a cover sheet/interleaved sheet key depressed to insert a cover sheet, a back cover sheet, and an interleaved sheet into output sheets. Reference numeral 433 designates a reduced layout key depressed to copy a plurality of originals onto a single sheet on a reduced scale. For example, to copy four originals onto a single transfer sheet, “4 in 1” is designated, and to copy two originals onto a single transfer sheet, “2 in 1” is designated. Reference numeral 434 designates an OHP (overhead transparency feeding) insertion key depressed to designate a mode for automatically inserting an OHP sheet in copying an original thereon. This key also allows the user to select whether or not copying is made on the OHP sheet.

[0079] Reference numeral 435 designates a duplex/duplex copy key depressed to designate duplex/duplex copy wherein an original placed on the platen glass (original table glass) 202 shown in FIG. 2, referred to above, is divided into two regions, i.e. left and right, regions and each of these regions is automatically copied to a single transfer sheet (for example, this key is depressed to designate “book to open from right”, “book to open from left”, “upside-down sheet discharging”, or the like). Reference numeral 436 is an enlarged layout key depressed to undo originals subjected to copying in the reduced layout mode. Reference numeral 437 designates a multiple key depressed to select duplex/duplex copy in a multiple mode, a duplex/duplex copy multiple mode, or the like. Reference numeral 438 designates an original consolidating key depressed to process differently sized originals placed on the RDF (original feeder) 201 shown in FIG. 2, referred to above.

[0080] Reference numeral 439 designates a photo key depressed to copy photographs.

Reference numeral 441 designates a close key depressed to close the application mode screen 400 b. When this key is depressed, the basic screen 400 a shown in FIG. 4, referred to above, is displayed on the touch panel 316. It should be noted that the “binding margin” and “border erasing” functions set by the favorite keys 420 and 415 displayed on the basic screen 400 a shown in FIG. 4 are the same as those set by the binding margin key 431 and the border erasing key 430 displayed on the application mode screen 400 b.

[0081] Next, a description will be given of screens displayed on the touch panel (liquid crystal display operating section) 316, shown in FIG. 3, referred to above, when the operator designates the size and type of sheets set on the manual feed tray 222 provided on the thus constructed digital copying machine according to the first embodiment, with reference to FIGS. 6 to 8 and to a flowchart shown in FIG. 13. FIGS. 6 to 8 are views showing examples of screens displayed on the touch panel 316 to designate sheet size and type for the manual feed tray as a device, and FIG. 13 is a flowchart showing a flow of a process of carrying out sheet size/type settings for the manual paper feed try as a device. The control section 109 executes the process shown in the flowchart of FIG. 13.

[0082] A screen (a) shown in FIG. 6 is displayed as a sheet size selecting screen on the touch panel 316 (step S132) when the user sets a sheet or sheets on the manual feed tray (YES at a step S131). When the user sets a sheet size through the screen (a) of FIG. 6 (step S133), a sheet type selecting screen (c) shown in FIG. 7 is displayed on the touch panel 316 (step S134). This screen (c) of FIG. 7 is displayed to prompt the user to set a sheet type (step S135).

[0083] The sheet size selecting screen is displayed on the touch panel 316 on the following conditions:

[0084] If the user sets a sheet or sheets on the manual feed tray;

[0085] If a sheet or sheets are found on the manual feed tray when the machine is turned on;

[0086] The screen is always displayed on top of a regular touch panel screens (only on the basic or default screen, sheet selecting screen, and application mode screen as far as copying is concerned);

[0087] The screen is displayed upon closing a screen that displays a dialogue box indicating that a job is being executed, during display of a dialogue box, and upon closing a user mode screen for changing basic settings of the system, a system status, a counter screen, or a status screen that displays a jamming message, a corporate division/section ID, a control card, a guidance message or the like;

[0088] The screen is displayed also when the user instructs starting a print job and sets a sheet or sheets on the manual feed tray after [Reserve Change to Manual Feed] has been made to reserve a change to manual feeding as the print job (sheet size/type settings already selected), to prompt the user to enter a sheet size again.

[0089] When the user depresses an OK button after entering the sheet size on the sheet selecting screen (a) of FIG. 6, the popped-up screen (“popping-up” is a function of displaying an instruction for an operation related to a desired item on a screen when the desired item is selected on the screen) is closed, followed by returning to a screen immediately preceding the popping-up. This operation of selecting the sheet size on the sheet size selecting screen is for setting the sheet size for the manual feed tray as a device, and therefore does not affect the sheet size for manual feeding for the print job, that is, the selected sheet size is registered only for the manual feed tray as a device. The manual feed tray is nor automatically selected as a sheet cassette for use. However, if the popping-up is activated by the user's operation when the copy basic screen, copy application mode screen or sheet selecting screen is displayed (by depressing a sheet selecting button on the copy basic screen), the sheet size entered through this sheet size selecting screen is registered not only for the manual feed tray as a device but also for manual feeding for a print job. Further, in this case, the manual feed tray is automatically set as the sheet cassette for use. To allow the user to confirm the change to manual feeding, a sheet selecting screen (d) shown in FIG. 7 is displayed on the touch panel 316 upon completion of the sheet size designation. Thus, the user can check that manual feeding is selected, and can also select a different sheet feed mode immediately when he or she so wishes, on this screen.

[0090] For copying, when the sheet size selecting screen for manual feeding is closed, the sheet selecting screen is displayed with the manual feeding selected. To change the sheet feeding mode from the manual feed tray as a device for use, the user is requested to remove or set a sheet or sheets on the manual feed tray. (A [Reserve Change to Manual Feed] key is depressed when the user desires to reserve a change to manual feeding as a job from manual feeding from the manual feed tray as a device.)

[0091] Next, a description will be given of screens displayed on the touch panel (liquid crystal display operating section) 316 when the operator carries out sheet size/type settings for manual feeding as a job in the digital copying machine according to the first embodiment with reference to FIGS. 9 to 12 and to a flowchart shown in FIG. 14.

[0092] FIGS. 9 to 12 are views showing examples of screens displayed on the touch panel 316 when the user carries out sheet size/type settings for manual feeding as a job. FIG. 14 is a flowchart showing a flow of a process of carrying out sheet size/type settings for manual feeding as a job. The control section 109 executes the process shown in the flowchart of FIG. 14.

[0093] When a sheet selecting key 410 is depressed on the basic screen (YES at a step S141), a screen (a) shown in FIG. 9 is displayed on the touch panel 316. In the sheet selecting screen (a) of FIG. 9, an area 601 displays information about paper (size/type/remaining number of sheets) (step S142). When there is no sheet on the manual feed tray 222, a manual feeding icon and a remaining sheet number icon (displayed as empty) are displayed, together with a message “THERE IS NO SHEET” on the status line similarly to sheet cassettes. When there is a sheet or sheets on the manual feed tray, displayed are sheet size and sheet type icons (including a sheet orientation icon) designated on the [Manual Feeding Sheet Designating] screen shown in FIG. 6, referred to above, the manual feeding icon, and the remaining sheet number icon (a triple line icon when there is only one sheet available).

[0094] Reference numeral 602 designates an automatic sheet selecting key depressed to select a sheet size corresponding to the original size and magnification set during sheet selection. Reference numeral 603 designates the [Reserve Change to Manual Feed] key depressed to set sheet size and sheet type for a job to be activated. The obtained settings are retained until reset/auto clear functions are started. Reference numeral 604 designates a manual feeding selecting key depressed to select manual feeding for printing for feeding of transfer sheets from the manual feed tray.

[0095] Reference numeral 605 designates a first cassette selecting key depressed to select a first cassette for feeding of transfer sheets therefrom for printing. Reference numeral 606 designates a second cassette selecting key depressed to select a second cassette for feeding of transfer sheets therefrom for printing. Reference numeral 607 designates a third cassette selecting key depressed to select a third cassette for feeding of transfer sheets therefrom for printing. Reference numeral 608 designates a fourth cassette selecting key depressed to select a fourth cassette for feeding of transfer sheets therefrom for printing. Reference numeral 609 designates a fifth cassette selecting key depressed to select a fifth cassette for feeding of transfer sheets therefrom for printing.

[0096] The [Reserve Change to Manual Feed] key 603 can be depressed even when no sheet is on the manual feed tray (the key is not shaded). Further, as long as a sheet or sheets are on the manual feed tray, this key 603 can be depressed even if manual feeding is not selected. When the [Reserve Change to Manual Feed] key 603 is depressed (YES at a step S143), a sheet size setting screen (c) shown in FIG. 11 is displayed on the touch panel 316 (step S144). The screen (c) of FIG. 11 is for prompting the user to set a sheet size for a job of designating manual feeding to be activated. When the user sets the sheet size (step S145), a sheet type selecting screen (e) shown in FIG. 12 is displayed (step S146). The screen (e) of FIG. 12 allows the user to select a sheet type for the job of designating manual feeding to be activated. When the sheet type is selected (step S147), a sheet selecting screen (f) shown in FIG. 12 is displayed.

[0097] Through the sheet selecting screen (f) of FIG. 12, the sheet size/type icons (including the sheet orientation icon) are reflected in the [Manual Feed] key. Upon designation of the sheet size and type, the manual feed tray is automatically selected (step S148). The [Manual Feed] key is then highlighted, while the [Reserve Change to Manual Feed] key is not highlighted. This is to allow the user to confirm that manual feeding is selected by displaying the sheet selecting screen after the user designated the sheet size and type (step S149), and to enable the user to select another sheet feeding mode immediately if he or she so wishes.

[0098] The manual feeding selecting key 604 displays a message “MANUAL FEED” when no sheet is on the manual feed tray. When a sheet or sheets are set on the tray, the sheet size/type icons (including the sheet orientation icon) designated through the [Designate Manual Feeding Paper] screen shown in FIG. 6, referred to above, are displayed, leaving the remaining sheet number icon undisplayed for the manual feed tray, because such information is not available due to the fact that the manual feed tray is provided only with a sensor for detecting the presence of sheets, not for counting the number of remaining sheets. When the [Reserve Change to Manual Feed] has been made, the designated size/type icons are displayed. Since this is the designation for a job to be activated, the user might wish to select different sheet size/type settings from those set for the sheet or sheets actually placed on the manual feed tray. The sheet size/type set for the manual paper feed tray is to be displayed on the area 601. When the manual feeding selecting key 604 is depressed, the manual feed tray is selected as the sheet feeding source for the job in question. The attributes of sheets, i.e. sheet size and sheet type set for the job in question are the same as those selected through the [Reserve Change to Manual Feed] key.

[0099] As described above, according to the digital copying machine of the first embodiment, there are provided the reader section 10, the facsimile section 106, the computer interface section 107 for inputting image data, the image memory 108 for sequentially storing the input image data, the printer section 104 for reading the stored image data from the image memory 108 to sequentially print the read image on sheets, the operating section 102 capable of displaying the copy basic screen and the copy application mode screen, and the control section 109 for controlling the image memory 108 to sequentially store the input image data, controlling the printer section 104 to sequentially print out hard copies of the stored image, and also controlling the process of determining whether or not the manual feed tray can be designated as the sheet feeding source if the user designates a sheet size by a device or a job, and selecting the manual feed tray as the sheet feeding source if it is so determined, and controlling the process of displaying the sheet selecting screen by the operating section 102, if the user designates a sheet size by a device or a job, to allow the user to confirm or change the selection of the manual feed tray as the sheet feeding source, upon completion of the sheet size designation. This configuration provides the following operations and results:

[0100] In the above configuration, when the user sets a sheet or sheets on the manual feed tray of the digital copying machine, the control section 109 displays the sheet size selecting screen on the touch panel 316 of the operating section 102. Then, the user designates a sheet size on the same screen. Responsive to the sheet size designation, the control section 109 then displays the sheet type selecting screen on the touch panel 316 of the operating section 102. The user now selects a sheet type on the same screen.

[0101] When the user depresses the sheet selecting key on the basic screen of the touch panel 316 of the operating section 102, the control section 109 displays, on the sheet selection screen, the screen related to paper (size/type/remaining sheets) set on the manual feed tray. When there is no sheet on the manual feed tray, the control section 109 displays the manual feeding icon and the remaining sheet number icon (displayed as empty), together with a message “THERE IS NO SHEET” on the touch panel 316 of the operating section 102. When there is a sheet or sheets on the manual feed tray, the operating section 109 displays the sheet size/type icons (including the paper orientation icon) designated on the manual feeding sheet designating screen, together with the manual feeding icon and remaining sheet number icon, on the touch panel 316 of the operating section 102.

[0102] The control section 109 then displays the screen allowing the user to set a sheet size for a manual feeding designating job to be activated, on the touch panel 316 of the operating section 102. When the user sets the sheet size, the control section 109 displays the screen requesting the user to select a sheet type for the same job on the touch panel 316 of the operating section 102. Once the user has designated the sheet size and type, the manual feed tray is selected automatically.

[0103] Further, the control section 109, after the user has designated the sheet size and type, displays the sheet selecting screen on the touch panel 316 of the operating section 102 to allow the user to confirm that the sheet feeding mode has been changed to manual feeding. If the user wishes to feed a sheet or sheets in any other mode than the manual feeding mode, the control section 109 displays the sheet selecting screen on the touch panel 316 of the operating section 102 so that the user can select a different sheet feeding mode immediately.

[0104] Therefore, in the first embodiment, when the user designates the sheet size for manual feeding, the copying machine, recognizing that a request has been made to execute manual feeding, automatically selects the manual feed tray as the sheet cassette, to thereby enable preventing a user from failing to carry out proper settings and hence avoid printing using an undesired sheet cassette. Further, to enable the user to check that the manual feed tray has been automatically selected, the machine displays the sheet selecting screen after the user has designated the sheet size for manual feeding, to allow the user to confirm the selection of the manual feeding mode, and if the user wishes to use a paper feeding mode other than the manual feeding mode while checking the screen, the user is allowed to select the other mode immediately on the screen.

[0105] Next, a second embodiment of the present invention will be described.

[0106] Before giving a detailed description of the second embodiment, the second embodiment will be summarized. According to the second embodiment, a reservation for the next print job is accepted during printing, a sheet or sheets for manual feeding from the manual feed tray are designated, the sheet or sheets for use per reserved print job are stored, and the type of the sheet or sheets is determined at the time of execution of each print job, and the printer section is controlled to print out hard copies in a manner according to the determined sheet type.

[0107] A digital copying machine (image forming apparatus) according to the second embodiment is constructed similarly to the digital copying machine according to the first embodiment shown in FIG. 1, that is, it is comprised of the digital copying machine main body 101 having the operating section 102, the reader section 103, and the printer section 104, and the image input/output control section 105 having the facsimile section 106, the computer interface section 107, the image memory 108, and the control section 109. The control section 109 of the section 105 is connected to the reader section 103 of the main body 101 (see FIG. 1 referred to above).

[0108] The second embodiment is different from the first embodiment in that the control section 109 controls a process of accepting a reservation for the next print job during printing, storing a sheet or sheets for use per reserved job based on designation of the sheet or sheets for feeding from the manual feed tray 222 per reserved print job, determining the type of the designated sheet or sheets at the time of executing each reserved print job, and controlling the printer section 104 to print out hard copies in a manner according to the determined sheet type, according to flowcharts shown in FIGS. 15 and 16. The second embodiment is otherwise identical with the first embodiment.

[0109] Further, the configuration of the reader section (see FIG. 2 described above), the configuration of the operating section (see FIG. 3 described above), various screens such as the copy basic screen and the copy application mode screen (see FIGS. 4 to 12 described above) displayed on the touch panel of the operating section of the digital copying machine according to the second embodiment are identical or similar to those of the first embodiment. Since the configurational particulars of FIGS. 1 to 5 referred to above have been described in detail with reference to the first embodiment, their description is omitted.

[0110] Next, a description will be given of the operation of the second embodiment, i.e. screens displayed on the touch panel (liquid crystal display operating section) 316 shown in FIG. 3, referred to above, when the operator designates the size and type of paper set on the manual feed tray 222 provided on the thus constructed digital copying machine according to the second embodiment, with reference to FIGS. 6 to 8 and to a flowchart shown in FIG. 15, while delineating their differences from those of the first embodiment.

[0111] FIGS. 6 to 8 are views showing examples of screens displayed on the touch panel 316 to carry out sheet size/type settings for the manual feed tray as a device, and FIG. 15 is a flowchart showing a flow of a process of carrying out sheet size/type settings for the manual feeding try as a device, which is executed by the control section 109. In FIG. 15, steps common to those in FIG. 13, referred to above, are designated by the same step numbers, and their description is simplified or omitted. The steps S131 to S135 are identical with those in the first embodiment.

[0112] The screen (a) shown in FIG. 6 is displayed on the touch panel 316 as the sheet size selecting screen when the user sets a sheet or sheets on the manual feed tray. This screen (a) of FIG. 6 allows the user to select a sheet size from regular A and B sizes (A3/A4/A5/B4/B5) or inch-based sizes.

[0113] When “POSTCARD” is depressed on the screen (a) of FIG. 6 (YES at a step S151), a postcard selecting screen (b) shown in FIG. 8 is displayed on the touch panel 316 (step S152). Upon selection of a postcard type on this screen (b) (step S153), the setting process is terminated since there is no need to select a sheet type. When the sheet size is selected on the screen (a) of FIG. 6, the sheet type selecting screen (c) of FIG. 7 is displayed on the touch panel 316, asking the user to select a sheet type on the same screen (c). Since conditions for displaying these screens are similar to those for the first embodiment, their description is omitted.

[0114] Operations to be performed after the selection of the sheet size with a depression of the OK button are similar to those of the first embodiment, except that the displayed screen returns to the sheet selecting screen when popping up another screen during display of any of the copy basic screen, copy application mode screen, and sheet selecting screen (displayed by depressing the sheet selecting button on the copy basic screen). Further, the sheet size for the job is automatically selected as that for the device, and the manual feed tray is also automatically assigned as the sheet cassette.

[0115] Next, a description will be given of screens displayed on the touch panel (liquid crystal display operating section) 316 when the operator designates the size and type of manual feeding sheet by a job for the digital copying machine according to the second embodiment, with reference to FIGS. 9 to 12 and to a flowchart shown in FIG. 16.

[0116] FIGS. 9 to 12 are views showing examples of screens displayed on the touch panel 316 to designate sheet size and type for manual feeding by a job, and FIG. 16 is the flowchart showing a flow of a process of designating sheet size and type for manual feeding as a job. The control section 109 executes the process shown in the flowchart of FIG. 16, in which steps common to FIG. 14, referred to above, are designated by the same step numbers, and their description is omitted or simplified. The steps S141 to S145 and the step S148 are identical with those in the first embodiment.

[0117] Since the display control process executed when the sheet selecting key is depressed on the basic screen is identical with that in the first embodiment, its description is omitted.

[0118] A second cassette selecting key 606 is depressed to select a second sheet cassette for feeding of transfer sheets therefrom during printing. When the key 606 is depressed, a screen (b) of FIG. 10 appears, and the setting operation is terminated by depressing a close key. Since the functions performed by other keys 602 to 605 and 607 to 609 have already been described with reference to the first embodiment, their description is omitted.

[0119] When the [Reserve Change to Manual Feed] key 603 is depressed, the screen (c) shown in FIG. 11 is displayed on the touch panel 316 for setting sheet size. The user thus can select a desired sheet size from the regular A and B sizes or inch-based sizes. When “POSTCARD” is depressed (YES at a step S161) on this screen (c), the postcard type selecting screen (d) is displayed on the touch panel 316 (step S162). When the user selects a postcard type on this screen (d) (step S163), the setting operation is terminated here since there is no need to select a sheet type.

[0120] The screen (c) of FIG. 11 allows the user to set a sheet size for a job of designating manual feeding to be activated. When the sheet size is set, the screen (e) shown in FIG. 12 is then displayed (step S164). This screen (e) allows the user to set a sheet type for the same job. When the sheet type is set (step S165), the setting operation is terminated. Upon closing the [Designate Manual Feeding Sheet] screen, the sheet size/type icons (including the sheet orientation icon) are reflected in the [Manual Feed] key 604. The process of selecting the manual feed tray as the sheet feeding source for the job in question similarly applies as it does to the first embodiment.

[0121] As described above, according to the digital copying machine of the second embodiment, there are provided the reader section 103, facsimile section 106, and computer interface section 107 for inputting image data, the image memory 108 for sequentially storing the input image data, the printer section 104 for reading the stored image data from the image memory 108 to sequentially print hard copies of images on sheets, the operating section 102 capable of displaying the copy basic screen and the copy application mode screen, and the control section 109 for controlling the image memory 108 to sequentially store the input image data, and controlling the printer section 104 to sequentially print out the stored image data, and controlling the process of accepting a reservation of the next print job during printing, the process of storing a sheet or sheets for use per reserved job based on the designation of the sheet or sheets for feeding from the manual feed tray, the process of determining the type of the designated sheet or sheets at the time of execution of each job, and the process of printing hard copies in a manner according to the determined sheet type. Therefore, the digital copying machine according to the second embodiment can provide the following operations and results.

[0122] In the above configuration, when the user sets a sheet or sheets on the manual feed tray of the digital copying machine, the control section 109 displays the sheet size selecting screen on the touch panel 316 of the operating section 102. Then, the user designates a sheet size on the same screen. Responsive to the sheet size designation, the control section 109 then displays the sheet type selecting screen on the touch panel 316 of the operating section 102. The user now selects a sheet type on the same screen.

[0123] When the user depresses the sheet selecting key on the basic screen of the touch panel 316 of the operating section 102, the control section 109 displays, on the sheet selection screen, the screen related to paper (size/type/remaining sheets) set on the manual feed tray. When there is no sheet on the manual feed tray, the control section 109 displays the manual feeding icon and the remaining sheet number icon (displayed as empty), together with a message “THERE IS NO SHEET” on the touch panel 316 of the operating section 102. When there is a sheet or sheets on the manual feed tray, the operating section 109 displays the sheet size/type icons (including the paper orientation icon) designated on the manual feeding sheet designating screen, together with the manual feeding icon and remaining sheet number icon, on the touch panel 316 of the operating section 102.

[0124] The control section 109 then displays the screen allowing the user to set a sheet size for a manual feeding designating job to be activated, on the touch panel 316 of the operating section 102. When the user sets the sheet size, the control section 109 displays the screen requesting the user to select a sheet type for the same job on the touch panel 316 of the operating section 102. When the user has designated the sheet size and type, the setting process is terminated.

[0125] Therefore, in the second embodiment, when a sheet or sheets are being fed or to be fed from the manual feed tray during printing or for a reserved print job, or when the manual feed tray is being used by the preceding print job, the user can designate a sheet or sheets to be set on the manual feed tray for a print job or print jobs to be reserved. For example, by designating the size and type of sheets such as a postcard, OHP sheet, and thick sheet for printing jobs to be reserved, the digital copying machine can smoothly process printing through manual feeding in different manners according to a plurality of jobs, whereby the printing can be performed efficiently.
